(ol. 21o- 54) 1 Claim.

This invention relates to new and useful improvements in fuel separators and more particularly to an` apparatus for separating gasoline, kerosene, Diesel fuel, or other liquids having various specific gravities diierent from water.v

The principal object of the present invention is to provide a simple and inexpensive device which will be positive acting and not susceptible to the ready development of defects.

Other objects and advantages of the invention will become apparent to the reader of the fol-- I lowing specification.

view substantially on the line 6;-6 of Figure 3.

Referring to the drawings, wherein like nu'- merals designate like parts, it can be seen that the separator consists of a cylindrical tank 5 having a fuel inlet pipe 6 and an outletppe 1. This tank has a flanged upper end 8 to which a cap plate 9 is secured by screws or bolts IIJ.

The bottom of the tank is of hemispherical shape and has the seat and guide body II' in the central portion thereof. A portion of this body extends upwardly into the bottom portion of the tank as at I2. A bore I3 extends vertically through the body II and the upper interior vof thisbody is beveled to denne a seat I4 against which a tapered valve structure I5 is operative. This ,valve element I5 has a depending hollow stem I6, this stem having openings I'I in the lower end thereof through which a stop pin I8 is disposed to limit rising of the valve. Y

The top of the valve structure I5 is concaved toreceive a oat I9. This oat canbe other means to the valve structure I5. Ports 20 open through thel sides of the stem I6 from the interior of the stem I3 immediately at the merging point of the stem with the valve structure I5.

As can be seen, the oat I9 assumes the position shown in Figure2 when there is but a small amount of water or no water in the bottom of the tank. Due to the difference in specific gravity, water will remain below various kinds of oils such as are used for fuel, and in the operation of the present apparatus, in the event the water content of the tank 5 increases sufficiently to float the float I9, the valve structure I5 will be lifted fromv the seat I4 and the water will be4 permitted to discharge through the stem I6.. As the water is drained, the iloat I9 will again settle on the seat I4, as itis to be understood that the float I9 is too heavy to float in liquid of the specic gravities of gasoline, kerosene, Diesel fuel, etc.

While the foregoing specification sets forth the invention in specific terms, it is' to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the claimed as new isv A device for separating water from liquid fuel comprising a tank having a substantially semispherical bottom, a body depending from the bottom of the tank and having a portion extending slightly into the tank, said body having a longitudinally extending bore therein and an inverted conical recess in its top with which the bore communicates, a. iioatin the tank of greater weight than the liquid fuel to be placed in the tank but buoyant in water, a substantiallyconportion of a spherical-shaped hollow secured by welding or ical 4valve forming member connected with the lower part of the oat and engaging the conical recess when the float is in lowered position and a tubular stem extending downwardly from the valve forming part and having a lateral opening at its point of junction with the valve forming part for communicating the interior of the. stem with the interior of the tank when the o'at is in raised position, said stem having a sliding fit in the bore of the body vfor guiding the oat in its movement. 5
